Boyfriend advice

I need help with my relationship. We've been dating for almost 9 months and he told me he doesn't feel like he's a priority or that I love him as much as he does. I don't know what else do that would show him any of these things, I already text and call him to check up on how he's doing and I go to his house all the time and invite him places whenever I want to go somewhere. What is your best relationship advice?
